Sam, I wonder how close dyno results are from
place to place. I have pretty close to the same
setup as you but my numbers are different. I
don't feel my rockers gained me much because my
track times did not fall. The MSD and pulleys
droped my time by 3/10 of a second, I can see 10
hp but I hardly think thats 20 lb/ft of torque?
especially since you tested with headers?
What kind of track times do you get? 14.8 was my
best, but I am pretty consistant at 14.9 - 15.0.
Dyno run #1
max power = 221.2 max torque = 294.7
Dyno run #2 (removed air filter)
max power = 222.2 max torque = 294.5
